Making Calls with the VIU-3236-10Making a BRI call through Two Gateways to a Remote LANEndpointIf the bandwidth of the calling VIU-323 is 2x64 Kbps and the receiving VIU-323’sbandwidth is 384 Kbps, dial:! The first gateway’s service number, followed by! The phone number of the remote gateway;When you are prompted by an IVR message (for example), dial:! The extension of the remote VIU-323, followed by! The dialing suffix.Example80 7654321 (IVR prompt) 4444 00Where 80 is the service prefix of the first gateway, 7654321 is the phone number of theremote gateway, 4444 is the extension of the remote VIU-323, and 00 changes the receivingVIU-323’s bandwidth to 2x64 Kbps.Changing Both Incoming and Outgoing BandwidthIn some cases, you must dial both a prefix and a suffix. Because the network sets bandwidthavailability at any particular time, you may have to use lower bandwidths during peakhours. You may therefore have to use a prefix to force the outgoing call to a lowerbandwidth and a suffix so that the VIU-323 you are calling can receive the call. Rememberthat you can only use a suffix when calling from one VIU-323 to another.ExampleIf both VIU-323’s are set to 384 Kbps, but the call doesn’t go through, send the call at 128Kbps by dialing the following:#10 80 7654321 (IVR prompt) 4444 10Where #10 changes the calling VIU-323’s bandwidth to 128 Kbps, 80 is the service prefixof the first gateway, 7654321 is the phone number of the remote gateway, 4444 is theextension of the remote VIU-323 and 10 changes the receiving VIU-323’s bandwidth to128 Kbps.Note: The dialing suffix (when used) must match the dialing prefix (when used); forexample, when the prefix is #20, the suffix, if necessary, must be 20; when the prefixis #00, the suffix, if necessary, must be 00.
